As much as I don't care for this practice, so long as the the school isn't promoting or leading the prayer, it's technically legal. The only ground they may have is if the school requires adults and visitors to check in and carry a pass to be on school property. If so, the pastors presence is approved and his prayer meeting condoned in a way.

Kevin, It's my understanding that if the kids were doing this independently, there is no legal issue, as it isn't being endorsed by the school. Like if a kid wants to pray before a test... But the problem is when the school requires and endorses prayer as part of an assembly, sporting even, graduation , or what have you. If it were just some kids that decided to meet at the flag pole to pray, and the school had nothing to do with it, I don't feel that's a church/state issue. In that scenario, kids of all different faiths could also do the same if the school isn't involved in the meetings. But the addition of the pastor on school grounds does complicate things. I could be wrong though. It was my assumption that the school had to be complicit for it to be a breech. But if there is an established body that shows otherwise, then I stand corrected. I agree that they shouldn't do this at school. There's a time and place for everything. Prayed belongs at home or church, not the school. Thanks again for correcting me, as I was unaware that the school needn't have to be involved for it to be a breech of church/state.

I went to school in Florida, and the school had a teacher-led "non-denominational" but very Christian Agape Club, held during school hours set aside for clubs like Chess Club, Anime Club, and Debate Team.

The leader of my high school's Agape club was actually my science teacher. Ha ha.
